GAS FUEL BURNER.

SPECIFICATION forming part of Letters Patent No. 380,913, dated April 10, 1888.

Application filed August 36, 1887. Serial No. 247,987. (No model.)

To aZZ whom it may concern.-

Be it known that I, CHARLES H. MILLER, a citizen of the United States, residing at Erie, in the county of Erie and State ofPennsylvania, have invented certain new and useful Improvements in Gas-Fuel Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

My invention relates to gas-fuel burners; and it consists in the improvements hereinafter set forth and explained, and illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of my improved gas-fuel burner with a portion of the top thereof broken away. Fig. 2 is a like view ofa section of a modified form of same with a portion of the top thereof broken away. Fig. 3 is a perspective view of the interchangeable collar for connecting the gas-inlet pipe to the burner. Fig. 4. is a perspective View of the interchangeable cap-plate for closing one of the gas'inlet openings.

Like letters refer to like parts in all of the figures.

The objects of my invention are to construct a gas-fuel burner with a corrugated top, the corrugations being hollow and projecting above the surface of the top of the burner, and also to construct a gas-fuel burner with center gas-inlet and end gas-inlet openings, and interchangeable collars and caps for said openlugs.

Other features of my invention appearhere inafter in the specification and claims.

In the constructionof my improved gas-fuel burner I make the base A in the form of a flat plate, having a central gas-opening, B, therein and an upwardly-projecting flange, 0, around the edge thereof, so that the top D of the burner will preferably fit inside of the flange C, so that the joint will not tend to open by the expansion of the top D of the burner. The top D of the burner I cast with corrugations E, and I also provide gas-outlet openings F at the ends of said corrugations. These corrugations E project some distance above the surface of the top of the burner, and are hollowed out on their under surfaces, so that they are no thicker than other portions of the top, forming heating-chambers in which the gas enters on its way to the outlet-openings F,where itis heated and expanded by means of the action of the heat upon these corrugated surfaces. The gas outlet openings F, I make at the outer ends of the corrugations E, and am by this construction enabled to cast the top D of the burner with all of the outlet-openings F complete therein without further finishing. The outletopenings F are of oblong shape, which renders them more easily cast, and at the same time less liable to become obstructedin use by ashes, or by clinkers or other non-combustible material placed on the burner to diffuse the heat from the gas-flame. The corrugations E also operate to better distribute the gas to the different outletopenings F, as they operate as channels or guides thereto, and in constructing the top D corrugated in this manner I make the entire top of substantially equal thickness, so that it is much less susceptible to damage from the action of heat thereon.

On one end of the top D, I cast an enlargement, G, adapted to receive either the collar H, Fig. 3, or the cap-plate I, Fig. 4, as illustrated in Figs. 1 and 2. This collar H and cap-plate I are made interchangeable, so as to be secured to either. the enlarged portion G of the top D-by means of the bolts J J, or to the opening B in the base A by means of thebolts h, so that when the burneris being placed in a stove or grate the gas-inlet pipe may be secured thereto either at the center of the basesection of the burner or at the end of the burner, this being made necessary by the construction of the stove or grate being such that the gassupply pipe has in some cases to be brought through the side of the stove to the end of the burner, while in others it can be brought up through the base to t-hecenter of the burner, making such variations in the connections imperative.

In the drawings I show. the form of burner ordinarily used in ranges and grates; but Ido not desire to limit myself to this particular form of burner, as my invention is equally ap plicable to oval and round burners for heatingstoves.

Having thus described my invention, so as to enable others to make and use the same,what

I claim as new, and desire to secure by Letters ing, and a top section having an end gas-inlet Patent of the United States, isopening, with an interchangeable cap for said 1. The combination, in agas-fuel burner, of gas-inlet openings, substantially as and for the an upper or top section having hollow corrupurpose set forth. 5 gations projecting above the plane of said top In testimony whereof I affix my signature in r 5 and gasontlet openings at the ends of each of presence of two witnesses.

said corrugations,with abase secured thereto, CHARLES H. MILLER. substantially as and for the purpose set forth. Witnesses:
